Why are my tree's leaves turning yellow in Arizona?

It's usually chlorosis — our alkaline desert soil locks up iron and manganese so the roots can't absorb them, even when the nutrients are present. Deep-root feeding with chelated micronutrients delivers them in a form the tree can actually use.

How often should I fertilize my trees?

Most desert landscape trees benefit from feeding once or twice a year, typically spring and fall. We'll recommend a schedule based on the species and how stressed the tree is.

Is deep-root feeding better than spikes or surface fertilizer?

Yes. Surface granules and spikes often never reach the active roots in our hard, fast-draining soil. Pressurized deep-root injection puts the nutrients right where the feeder roots are.

Can fertilization save a tree that's already struggling?

Often, yes — if the problem is nutritional and the tree isn't too far gone. We'll assess it honestly; if the issue is disease, root rot, or watering, we'll tell you that instead.

“Our ficus was yellowing in the summer heat. The arborist deep-root fed it and walked us through a watering schedule. It greened right back up. (TODO: real review)”

Tree Fertilization (Deep-Root Feeding) Where You Live in the West Valley

Goodyear soil is alkaline almost everywhere, and the caliche layer under Estrella, Canyon Trails, and the newer Centerra and Sarival lots makes it worse: iron and manganese are in the ground but locked up where roots can't use them. The result is the same yellow-leaf citrus and ficus we see all over Palm Valley and the older Litchfield Rd neighborhoods, and the 'frizzle top' on queen palms in PebbleCreek and Estrella, which is a manganese deficiency, not a watering problem. Trees on turf lawns get nitrogen from the lawn fertilizer but rarely the micronutrients they need. Deep-root injection is how we get past the hardpan and into the feeder roots.
